Risk levelHigh

0–100, higher is better. How it is calculated

Kyosun s.r.o. operates the website www.matchatea.cz, a professionally designed e-commerce platform specializing in organic Japanese matcha tea products. The company targets health-conscious consumers interested in authentic matcha tea, offering a range of products, recipes, and educational content. The website demonstrates strong market positioning within the Czech Republic's niche organic tea retail sector, supported by multiple product awards and active social media engagement. Technically, the site is built on WordPress with modern SEO and performance optimizations, including Yoast SEO Premium, WP Rocket, and Google Tag Manager integration. Security posture is solid with HTTPS enforced and cookie consent mechanisms in place, though some security headers could be improved. Privacy compliance is well addressed with a comprehensive cookie policy and GDPR consent. WHOIS data is unavailable, likely due to privacy protection, but the overall trust indicators and business information support legitimacy. Strategic recommendations include enhancing security headers, publishing a security.txt file, and maintaining regular audits of third-party scripts.

This scan rated NIS2 with an earlier keyword method that is no longer shown; rescan for the per-article view. Risk management, continuity, supply chain, training, MFA, management oversight (Art. 20) and incident reporting (Art. 23) need internal evidence, and Guard cannot tell whether NIS2 applies to this organisation.

GDPR is indicative only, based on publicly visible signals: Articles 7, 12, 13 and 32 of Regulation (EU) 2016/679 and Article 5(3) of the ePrivacy Directive. Not a certification or legal assessment.

Priority findings

10 findings rated critical or high. Fix these first.

  1. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • Critical

      EU business without adequate privacy measures

      EU businesses are subject to strict GDPR requirements

      What to do: Implement comprehensive GDPR compliance including privacy policy, cookie consent, and data protection measures

    • High

      No Privacy Policy found

      GDPR requires a clear and accessible privacy policy

      What to do: Add a comprehensive privacy policy page and link to it prominently

  2. Security headers

    Security headers are instructions your web server sends to every visitor’s browser. Missing ones leave visitors more exposed to attacks such as clickjacking and injected scripts.

    • High

      Missing Strict-Transport-Security header

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

Results by check

Each check with its score, findings and the evidence it collected.

How this score is calculated

The security score runs 0–100, higher is better. It is the plain average of the security checks that completed in this scan, each counted equally. A check that could not run is left out: it counts neither as a pass nor as a fail.

Not counted

  • NIS2 outside view: Re-weights evidence from the TLS, email, DNS, network and hygiene checks, so counting it would count that evidence twice. Shown on its own.
  • OffSeq Observations: An AI reading of the site, useful context but not reproducible evidence. Shown on its own.

Findings that cap the score at 49

Each of these is serious on its own, so while any is present the site cannot rate better than high risk, however good the other checks are.

  • The certificate is not trusted by browsers
  • The website is not served over HTTPS
  • A database, remote desktop, file-sharing or Telnet service is reachable from the internet
  • The page loads a script from a compromised source
  • The domain registration has expired
  • SPF authorises every server to send mail as the domain

Partial scans

When the site blocks Guard or most checks cannot run, the score covers only the checks that ran (usually DNS and email), is capped at 75 and is shown as partial, without a risk level.

Technical appendix

Business context, site observations and technical notes gathered during the scan, and the standards behind each reference.

Business context

Business profile

The company operates a focused retail business model selling premium organic matcha tea products primarily through its website and wholesale channels. Its competitive advantage lies in product authenticity, quality certifications, and a strong brand presence supported by awards and customer reviews. The target audience includes health-conscious individuals and tea enthusiasts in the Czech Republic and neighboring countries. The business leverages content marketing via recipes and blog posts to engage customers and drive sales. Partnerships include a dedicated e-commerce domain (matchatea.bio) for direct sales. Growth indicators include consistent product recognition and active social media channels. The company maintains a small but professional digital footprint with opportunities for expansion in marketing and security maturity.

Security posture

The website exhibits a mature security posture with HTTPS enforced and no visible exposure of sensitive data. Cookie consent and privacy mechanisms align with GDPR requirements. However, the absence of key security headers such as Content-Security-Policy and X-Frame-Options represents an area for improvement. No incident response or vulnerability disclosure information is publicly available, which could be enhanced to improve transparency and trust. The use of Google Tag Manager and third-party analytics is controlled but requires ongoing monitoring to mitigate risks from external scripts. Overall, the security posture is good but can be strengthened with additional headers and formalized vulnerability disclosure processes.

Recommendations

  1. Implement comprehensive security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  2. Publish a security.txt file to facilitate responsible vulnerability disclosure and incident reporting.
  3. Regularly audit and update third-party scripts and plugins to mitigate potential vulnerabilities.
  4. Enhance privacy policy details to explicitly cover data retention and user rights.
  5. Maintain active monitoring of analytics and marketing tools to ensure compliance with privacy regulations.

Technical notes

Notes

The website is built on a WordPress CMS platform using modern technologies such as Yoast SEO Premium for search optimization, WP Rocket for caching and performance, and Google Tag Manager for script management. The site is mobile-optimized with responsive design and accessibility features. Performance is fast with preloading and lazy loading techniques implemented. The technical infrastructure is robust for a small retail business, though hosting provider details are not explicitly identified. The site uses external services for analytics and fonts, which are well integrated. Opportunities exist to improve security headers and formalize incident response capabilities to reduce technical risks.
Standards and sources

Reference chips under each finding point to the standard, regulation or specification the finding relates to. They are taken from the official datasets below and mapped conservatively: a finding with no defensible link shows none. NIS2 and GDPR references mark where a finding is relevant evidence, not a compliance verdict. Implementing Regulation (EU) 2024/2690 binds digital infrastructure and digital service providers; for other entities it is the most detailed public reading of the Article 21 measures. WCAG, EN 301 549, European Accessibility Act and Web Accessibility Directive references name the requirement an automated accessibility rule relates to; they are not a conformance verdict.
